Measuring chopped nuts accurately
Chop size dramatically changes how nuts fill a cup, so coarse pieces leave big gaps while fine ones pack tight. Spoon them in loosely and level. Because of that variability, weighing 120g per cup is the only way to measure chopped nuts consistently.
How many grams is 1 cup of chopped nuts?
About 120 grams — that is the figure to use when a recipe just says "1 cup chopped nuts" without naming the nut, and it is close to the truth for all of them. USDA measured the common nuts one at a time and chopped cups sit in a narrow band: chopped pecans 109 g, chopped hazelnuts 115 g, chopped walnuts 117 g, walnut pieces 120 g and chopped black walnuts 125 g. So half a cup of chopped nuts is about 60 g, a third of a cup 40 g, a quarter cup 30 g — and 100 g is about 0.83 cups. The prep state, not the species, is what really moves the number:
| Nuts, as prepared | 1 US cup | 1/2 cup | 1/4 cup | 100 g = |
|---|---|---|---|---|
| Chopped nuts, kind unspecified (this page) | 120 g | 60 g | 30 g | 0.83 cups |
| Walnuts, chopped | 117 g | 58.5 g | 29.3 g | 0.85 cups |
| Walnut pieces or chips | 120 g | 60 g | 30 g | 0.83 cups |
| Walnuts, shelled halves | 100 g | 50 g | 25 g | 1 cup |
| Walnuts, ground | 80 g | 40 g | 20 g | 1.25 cups |
| Black walnuts, chopped | 125 g | 62.5 g | 31.3 g | 0.8 cups |
| Pecans, chopped | 109 g | 54.5 g | 27.3 g | 0.92 cups |
| Pecan halves | 99 g | 49.5 g | 24.8 g | 1.01 cups |
| Almonds, whole | 143 g | 71.5 g | 35.8 g | 0.7 cups |
| Almonds, slivered | 108 g | 54 g | 27 g | 0.93 cups |
| Almonds, sliced (flaked) | 92 g | 46 g | 23 g | 1.09 cups |
| Almonds, ground (almond meal) | 95 g | 47.5 g | 23.8 g | 1.05 cups |
| Hazelnuts, whole | 135 g | 67.5 g | 33.8 g | 0.74 cups |
| Hazelnuts, chopped | 115 g | 57.5 g | 28.8 g | 0.87 cups |
| Hazelnuts, ground | 75 g | 37.5 g | 18.8 g | 1.33 cups |
| Cashews, dry-roasted halves and whole | 137 g | 68.5 g | 34.3 g | 0.73 cups |
| Pistachios, shelled kernels | 123 g | 61.5 g | 30.8 g | 0.81 cups |
| Macadamias, whole or halves | 134 g | 67 g | 33.5 g | 0.75 cups |
| Brazil nuts, whole | 133 g | 66.5 g | 33.3 g | 0.75 cups |
| Pine nuts | 135 g | 67.5 g | 33.8 g | 0.74 cups |
| Peanuts, raw shelled | 146 g | 73 g | 36.5 g | 0.68 cups |
USDA FoodData Central measured cup portions: English walnuts (#170187), black walnuts (#170186), pecans (#170182), almonds (#170567), hazelnuts (#170581), dry-roasted cashews (#170571), pistachio kernels (#170184), macadamias (#170178), Brazil nuts (#170569), pine nuts (#170591), raw peanuts (#172430). Half-cup, quarter-cup and 100 g figures are computed from the cup weight.
Read down that table and the surprise is that chopping does not push the weight in one direction — it depends on the shape of the nut you started with. Nuts sold as big curved halves get heavier per cup when chopped, because the small pieces drop into voids that halves cannot fill: walnuts go from 100 g a cup as halves to 117 g chopped, pecans from 99 g to 109 g. Compact, roughly spherical nuts go the other way, since cutting a good-packing sphere into angular flakes only adds air: whole hazelnuts 135 g a cup against 115 g chopped, whole almonds 143 g against 108 g slivered and just 92 g sliced.
That is also why the comma in a recipe matters. "1 cup chopped nuts" means chop first, then measure; "1 cup nuts, chopped" means measure whole, then chop. With walnuts the two readings differ by about 17% (117 g versus 100 g) — enough to matter in a batter that is already short on structure. Grinding exaggerates the same effect in the opposite direction: a cup of ground nuts is far lighter than a cup of whole ones — ground walnuts 80 g, ground hazelnuts 75 g, ground almonds 95 g. Ground almonds are exactly what almond meal and almond flour are, and our flour page's 96 g per cup lines up with USDA's 95 g measurement.
One honest caveat about nut weights generally: because nuts are irregular and vary by size grade and lot, published figures spread more than they do for flour or sugar — 10–15% between sources is normal. Raw cashews are the clearest example: US bag labels for whole raw cashews almost all print 1/4 cup = 28–30 g (112–120 g per cup, where our cashews page sits), while USDA's only measured cup portion is the 137 g dry-roasted entry above. Our hazelnut and pine nut pages use the baking-chart convention of 142 g against USDA's 135 g and 135 g for the same reason. None of that spread changes a cookie; all of it argues for the scale when the ratio matters. The grams to cups converter runs it backwards from any pack weight, the recipe scaler handles a doubled batch, and the baking conversion chart has the 100 g reverse lookups for nuts and seeds side by side.

How many grams is 1 cup of chopped nuts?
About 120 grams — the working figure for the generic "1 cup chopped nuts" a cookie, brownie or banana-bread recipe means. USDA measured the common ones individually and they land in a tight band: chopped pecans 109 g per cup, chopped hazelnuts 115 g, chopped walnuts 117 g, walnut pieces 120 g and chopped black walnuts 125 g. Anything in that 109–125 g range is defensible, so half a cup is about 60 g and a quarter cup about 30 g whichever nut you use.
Is "1 cup chopped nuts" the same as "1 cup nuts, chopped"?
No, and the comma is the whole difference. "1 cup chopped nuts" means chop first, then measure the pieces; "1 cup nuts, chopped" means measure the whole nuts, then chop them. With walnuts that is 117 g versus 100 g — about 17% more nuts in the first reading, because the pieces fill the gaps that curved halves leave. If the recipe is ambiguous, chop-then-measure is the more common intent in US baking, and weighing removes the question entirely.
Do nuts weigh more chopped or whole?
It depends on the shape of the whole nut, which is why there is no single rule. Nuts that come as big curved halves gain weight per cup when chopped, because the small pieces fill the voids: walnut halves 100 g per cup versus 117 g chopped, pecan halves 99 g versus 109 g chopped. Compact round nuts go the other way, since chopping turns a well-packing sphere into angular flakes: whole hazelnuts 135 g versus 115 g chopped, whole almonds 143 g versus 108 g slivered and 92 g sliced.
How many grams is 1 cup of ground nuts?
Much less than you would guess — grinding always makes a cup lighter. USDA measures ground walnuts at 80 g per cup (against 100 g for halves), ground hazelnuts at 75 g (against 135 g whole) and ground almonds at 95 g (against 143 g whole). Ground almonds are the same thing as almond meal or almond flour, which this site lists at 96 g per cup — near-identical to USDA's 95 g. So a recipe asking for "1 cup ground nuts" wants roughly a third less nut by weight than one asking for a cup of whole ones.
How many grams is 1 cup of chopped walnuts or chopped pecans?
Chopped walnuts are about 117 grams per US cup and chopped pecans about 109 g (USDA measured both). Half a cup is therefore 58.5 g of walnuts or 54.5 g of pecans, and a quarter cup 29.3 g or 27.3 g. Buying them as halves instead? A cup of walnut halves is 100 g and a cup of pecan halves 99 g.
How many cups is 100 grams of chopped nuts?
About 0.83 cups — a little over 3/4 of a cup. Working from other common pack sizes: 200 g is about 1.67 cups, 250 g about 2.08 cups, and 500 g about 4.17 cups. A US cup of chopped nuts is roughly 4.2 oz, so a 1 lb (454 g) bag holds about 3.78 cups.
Should I weigh nuts before or after toasting?
Before, if the recipe gives a weight and you are toasting them yourself. Toasting drives off moisture, so the same nuts weigh a little less afterwards — a few percent — and the recipe's gram figure was almost certainly written for raw nuts. The bigger effect is chop order: toast whole or in halves for even colour, then chop and weigh only if the recipe says "chopped nuts" rather than "nuts, chopped".
